ABSTRACT:
Conversion encoding coefficients which are accumulated in an input memory and read out from the memory is input into converting unit. Conversion matrix integration unit multiplies a basis matrix of conversion encoding coefficient by, arbitrary interpolation matrix or thinning matrix which is input from resolution conversion matrix inputting unit and sampling conversion matrix inputting unit to produce a converting matrix, and outputs the same to the converting unit. Alternatively, the conversion matrix integration unit selects a converting matrix which is previously calculated and stored in the memory, and outputs the same to the converting unit. The converting unit inputs the converting matrix from the conversion matrix integration unit and the conversion encoding coefficients from the input memory, and achieves the resolution conversion and sampling conversion by matrix product computation of the conversion encoding coefficients in row unit.
